Answer:
16 feet
Step-by-step explanation:
We use Pythagorean Theorem to find the height.
leg of triangle= height of ladder = 15 feet
The hypotenuse of the formed triangle = length of ladder = L
base = 6 feet
What is length of ladder?
L^2 = 15^2 + 6^2 = 225 + 36 = 261
L = root(261) = 16.155 feet
So first you take the number already read, in this case 573 books.
Next you take the goal, 900
Do the Goal minus the amount done:
900-573=327
